From your boot.log: igb: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX igb: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX One other piece of info (in addition to what Bruce requested) that would be useful is after you've done ifconfig eht0 up, cat /proc/interrupts | grep eth0 and send that output (I want to see your MSI-X configuration).
